7 '0 all whom it may concern:

lie it known that I, SAMUEL \V. (iouooN;

a citizen of the United States, rcsidin r at. Newark, in the county ofEssex and htate of New Jersey, have invented certain new and usefulImprovements in Universal Sterilizing-Stop-Cock Devices; and 1 dohereby.

declare the following to be a full. clear. and exact description of theinvention. such as will enable others skilled in the art to which it apertains to make and use the same.

T e invention relates to improvements in stop cocks. 1

The object of the present invention is to improve the construction ofstop cocks and to provide a simple, practical, and comparativelyinexpensive, universal sterilizing stop cock adapted to control thesupply of steam, hot water and cold water and equipped with means foradjustably maintaining the parts in a tight condition and capable ofaffording read access to the adjusting means when dosire With these andother objects in view the invention consists in the construction andnovel combination and arrangement of parts hereinafter fully described,illustrated in the accompanying drawings and pointed out. in the claimhcrctoappended, it being um derstood that various changes in the form,proportion and minor details of construction may be resorted to withoutdeparting from the spirit or sacrificing any of the advantages of theinvention.

In the drawing Figure 1 is a sectional view ,of a sterilin ing stop cockconstructed in accordance with this invention and shown applied to asink.

Fig. 2 is an enlarged longitudinal sec-- tional view through a modifiedform of the sterilizing stop cock.

Like numerals of reference designate corresponding parts in the severalviews of the drawings. i

In the accompanying drawing in which is illustrated the preferredcmlmdimcnt of the invention, the universal sterilizing stop cock whichis designed for use for sterilizing inst rmncnts and analogous purposescomprises in its construction an outer casing l of tubular i'orm taperedforwardly or outwardly and provided at. the top with a steam inletnipple 2 and having at the bottom ahot water inlet nipple 3 and a coldwate inlet nipple 4. These nipples are shown m the accompanying drawingas formed intcgral with the casing but they may consist of so )arateiieces threaded into the casing. '1 1e nipp e 2 is interiorly threadedfor the reception of the threaded end 5 of a steam pipe (5 which may beconnected with any suitable source of steam supply. The nipples 3 and 4are interiorly threaded for the reception of the'threaded ends 7 and 8of hot water and cold water pipes 9 and 10 connected with any suitablesource of supply. Within the casing 1 is arranged the rotary tubularvalve 11 provided with ports or openings 12. 13 and 14 adapted to bebroughu into register with the nipples 2. 3 and tend 79 as the openings12, 13 and'H are located at different points around the rotary tubularmember two of them will be out of register with their coacting nippleswhen one is brought into register with it. nipple. By this constructioneither hot water. cold water or steam may be supplied to the nozzle 15.The rotary tubular member has an outer extcriorly threaded end 16 whichis arranged within an enlarged terminal portion 17 of the casing and thesaid nut is adapted to bear against the coiled spring 18 interposedbetween the nut and the shoulder 10 formed by the inner end of theenlargement 1?. whereby the spring is adapted to hold tintapcrcd rotarymember into tight'engagr ment with the tapered casing to form a waicatight joint or connection between the said parts. Should the tubularmember heconr loose the nut is ada )ted to he tightel'ied -3 increasethe. tension iii the spring. The llw. which is preferably of octagonalform is a ranged within the extension 17 and the latt is exteriorlythreaded at 20 to receive an on lnrgcd cap portioiigl of the nozzle 15.The nozzle 15 by screwing pn the exterior of the enlargement 17 isadapted to be readily removed to afford instant. access to the adjusting means for maintaining the tubular memher in proper engagement withthe casing. 100

5 as required.

- In Fig. 1 is illustrated another form of the invention in which theouter casing 27 is oppositely ta ered from that shown in Fig. 2 and theen arged end is interiorly threaded 10 at 28 for the-reception of athreaded portion 29 of a nozzle 30. In this form of the invention whichis simpler than that illus- "trated in Fig; 2 the spring for urging thetapered rotary member into tight engagel; meiit with the casing isomitted.

The nozzle 30 in this form of the intern tion constitutes an adjustingmeans for maintaining the tapered rotary member in tight engagement withthe casing.

\Vhat is claimed is: A valve casin having an inlet 0 )ening, .a corerotatable t erein, having an inlet port and an axial outlet in one end,a nut threaded to the said end of the core, a spring bearing against thenut and casing for establishing a tight. tit between the core and casingand still Jermit free rotation of the Core, a screw threaded extensionon one end of said casing and overlying the spring and nut, a spent,

and an internally screw threaded enlargedportion on said spout forconnection with the extension.

In testimony whereof I al'lix my signature in presence of two witnesses.
